[Devel] [PATCH RH9 02/22] ve/net/sit: Enable SIT devices in Containers

[Andrey Zhadchenko]

From: Vasily Averin <vvs at virtuozzo.com>

Currently, we fail to create sit interface inside container,
because it has neither NETIF_F_VIRTUAL nor NETIF_F_NETNS_LOCAL:

  ipip6_tunnel_ioctl
   ipip6_tunnel_locate
    ipip6_tunnel_create
     register_netdevice
      ve_is_dev_movable

Mark sit as NETIF_F_VIRTUAL to fix this issue.
